五年级上册数学简便运算题?528-99 =528-(100-1)=528-100+1 =428+1 =429 4、1.2×2.5+0.8×2.5 解析:运用提取公因数的方法,公式:ac+ab=a(b+c),提取公因数2.5,1.2和0.8相加正好凑整数,使得运算简便。那么,五年级上册数学简便运算题?一起来了解一下吧。
简算运算。
(1)100+99+98-97-96+95+94-93-92+...+7+6-5-4+3+2-1=200
(2)(1+1/2+1/3+1/4)x(1/2+1/3+1/4+1/5)-(1+1/2+1/3+1/4+1/5)x(1/2+1/+1/4)=1/5
(3)9999*2222+3333*3334=33330000
(4)9999*7+1111*37=11110000
(5)3333*3333+9999*8889=99990000
(6)7.7*7+7.7+2*7.7=77
(7)125*25*3232*69=696900000
(8)14.8*6.3+45.5*4.5+8.3*3.7+0.465*550-6.3*6.5=548
(9)(2.5+2.5+2.5+2.5)*25*8=2000
(10)97*2000-96*2001=1904
一、计算:
1、竖式计算(得数精确到百分位)
8.63×0.42 0.38×2.6
2、脱式计算(能简算的要简算)
0.125×0.25×8×47.4×0.28+0.28×2.6
4.8×0.9+0.48 (4-0.4)×2.5
3、列竖式计算
4.83÷3 36.8÷16 59.51÷11
2、用竖式计算(并验算)
8.64÷829.29÷29 111÷0.37 24÷96
4、列竖式计算,并验算
2.862÷1.08 47.04÷0.56
4、用竖式计算(得数保留一位小数)
